IAPMO Introduces WDC-Pro to Streamline Multi-Family Design
IAPMO® has launched WDC-Pro, a web-based tool designed to improve the efficiency and accuracy of water pipe sizing for multi-family, high-rise, and residential buildings.
PRESS RELEASE
IAPMO and ASPE Co-publish Capacities of Stacks and Horizontal Drains in Storm Drainage Systems White Paper
Ontario, Calif. — The International Association of Plumbing and Mechanical Officials (IAPMO®) and the American Society of Plumbing Engineers (ASPE) have co-published White Paper 2-2024: Capacities of Stacks and Horizontal Drains in Storm Drainage Systems.
The sizing for storm drainage systems is dependent upon flow capacity equations used to calculate velocities and flow rates in pipe conduits. One of the variables in the equations is the coefficient of roughness. This white paper explores how the roughness of different types of material will change the computational results that are dependent upon the roughness coefficient of the pipe.
“Storm drainage systems play a vital role in building resiliency as they convey water off the roof, said IAPMO Vice President of Technical Services and Research Christoph Lohr, PE. “Studying storm piping systems is important to make sure these systems are not undersized, as the weight of water on a roof could exceed design parameters and fail, which could be catastrophic. With changing weather patterns, particularly rainfall rates increasing in many locations, revisiting assumptions and validating the equations of how storm piping systems are sized is vital. We are thankful to our partners at ASPE for collaborating with us on this white paper, which shows the depth of plumbing expertise exhibited by both organizations and their dedication to public safety.”

Austin, Texas, Adopts 2024 Uniform Codes
The Austin, Texas, city council has formally adopted the 2024 editions of the Uniform Plumbing Code (UPC®) and Uniform Mechanical Code (UMC®) as the plumbing and mechanical codes of practice protecting the health and safety of the city’s nearly 1 million residents. The Texas state capital and 11th most populous city in the United States has utilized the Uniform Codes since 1974.
Iowa Updates State Plumbing Code to 2024 UPC
The Iowa Public Health Department has updated Chapter 25 of the Iowa Administrative Code, “State Plumbing Code,” from the 2021 Uniform Plumbing Code (UPC®) to the 2024 edition. The update went into effect on March 26.
